Honors are in store for a South Bronx school still standing 100 years later.

St. John Chrysostom School — a Catholic institution as old as the Bronx itself — will mark a century of service Saturday.

The block where the school is located — Hoe Ave. between 167th and Home Sts. — will be co-named Dominican Sisters of Sparkill Place after the group that founded the school in 1914.

Archbishop Timothy Cardinal Dolan will join students, faculty and alumni at the celebration.

“We’ve gone through some hard times, but the church and the school are still here,” said Sister Mary Elizabeth Mooney, the school’s principal for the last 40 years. “We always say, ‘On the corner it might be violent, but in here it’s safe.’
